How to set up the VCS will depend on which VCS you choose - and won't have anything to do with STM32CubeIDE.
Or are you really asking how to integrate a VCS into STM32CubeIDE ?

How Version Control System works? How often it freeze and save files/state of a project? Does it restore to (a) hit 'commit' key (b) nth compile in past (c) at any time in past?
None of these has anything to do with STM32CubeIDE - it will be all down to the VCS you choose, how you choose to configure it, and/or how you choose to use it.

EDIT:
Note that a VCS doesn't need to be integrated with an IDE - any IDE - for you to use it on your projects.
